Some believe fight is looming over sweeping reforms after employment rights minister Justin Madders sacked and union allies sidelined

Keir Starmer has sought to tighten his grip on his government with a wave of junior ministerial changes that has sidelined allies of the unions, raising questions over the future of Labour’s workers’ rights package.

The reshuffle has been used by Downing Street to signal a tougher stance on immigration in an apparent bid to take on Reform UK, with Shabana Mahmood – a self-described social conservative rising star – now in charge of the Home Office, supported by Sarah Jones who returns to her former policing brief.

Justin Madders, the employment rights minister, was one of the first on the junior benches to be sacked on Saturday. Despite being seen as one of the architects of Labour’s “new deal for working people”, Madders’ departure was not formally announced in No 10’s list of appointments. Instead, he revealed the news himself.

“It has been a real privilege to serve as minister for employment rights and begin delivering on our plan to make work pay,” he said on X. “Sadly it is now time to pass the baton on – I wish my successor well & will do what I can to help them make sure the ERB is implemented as intended.”
